DEVICE FOR-CLOSING A BAG Filed Aug. 5, 1957 Patented Feb. 8, 1938 UNITEDSTATES PATENT OFFICE 4 Claims.

My invention pertains to devices for closing bags, pouches and otherreceptacles, and is herein illustrated in its application to arelatively small bag suitable as a container for a perfume 5 bottle.

The principal object of my invention is to provide simple and novelmeans for gathering and holding together the edges of the open end of abag.

10 Another object is to provide simple and efiicient means for drawingthe open end of a bag through a member which will retain it in agathered or closed position.

An additional object to which my invention is .15 directed is theprovision of means for keeping a closing member in convenientassociation with the bag with which it is to be used.

Certain additional objects, together with the many advantages of mynovel construction, will 20 be disclosed in the ensuing parts of myspecification.

With reference to the accompanying drawing:

Fig. 1 represents a front elevation of a bag with the closing device inan inoperative posi- 25 tion.

Fig. 2 is also a front elevation of the bag, but with its open end bentforward and in a partially closed position. Fig. 3 shows the bag incompletely closed posi- 30 tion with the closing device in its finaloperative position.

The illustrative embodiment of my invention comprises a rectangularlyshaped bag I which is open at its upper end. Any suitable flexiblematerial may be used in constructing the bag ID. A cord or loop memberl2 of a flexible nature has one end connected to a side of the bag It]at a point I4 near the top or open end. The other end of the cord [2 maybe connected to the bag 40 ill in a lower position IE, on the same side.

An identical cord or loop member i3 is connected similarly to the bag Inat points 16 and I! on the opposite side. i The cords l2 and [3 arethreaded or pass 45 loosely through a ring I I in the manner indicatedin Fig. 1 of my drawing.- Means for retaining the ring in permanentassociation with the bag are provided by the connections l5 and I1between the lower ends of the two loop mem- 60 bers and the bag. Whilemetal is a preferred material for'the ring H, celluloid, rubber, syn

thetic resin or other similar substancesmay be utilized. V I

'When the parts of the cords Hand l3 besuch as by the thumb andforcfingers of a pair of hands shown in Fig, 2, the extremities of thebag opening adjacent the points 14 and I6 are pulled progressivelythrough the ring ll (Fig. 2) This action gathers the other portionscompris- 5 ing the opening of the bag I!) to such an extent that theytoo readily follow the said extremities through the ring H. After thering H has moved downwardly a short distance the portions of the bagabove the ring U will be expanded 10 or spread'by continued pulling soas to retain said ring.

Fig. 3 shows the bag 10 in its completely closed position. It will beappreciated that the size of the ring II is determined by the amount ofthe bag material which must be circumscribed to efiect a closure.

The following is a description of a convenient manner of operating mydevice:

a. Gather the cords I2 and I3 below the ring l I, take one between thethumb and index finger of each hand, and pull.

1). Slide thumbs and index fingers closer to ring II, and pull until thebag is closed.

By using a pair of cords or loop members, I attain several novelfunctions which are not comprehended by any prior structures of which Iam aware: The ring is held in a convenient and centered position withrespect to the bag prior to being moved .to its operative position. Twoopposite extremities of the bag opening are guided smoothly through thering.

Although the invention has been described as embodied in a particularbag construction, it should be understood that the invention is notlimited in the scope of its application to any one form of receptacle.

Having described my invention, whatI claim as new and desire to secureby Letters Patent of the United States is:

1. A bag provided with an opening and having a closing device whichcomprises a pair of cords, an end of one cord being connected to the bagnear an extremity of the opening and an end of the other cord beingconnected to the bag near the opposite extremity of said opening, a ringthreaded on said cords, and means for retaining the ring in associationwith the bag. 7

2. A bag provided with an open end, a closing device comprising a pairof cords and a ring through which said cords are passed loosely, saidcords each being attached by an end to opposite extremities of the openend of the bag, and means for retaining the ring in association with Ythe bag. I v

3. A bag provided with an open end and having a closing "device whichcomprises a pair of loop members and a ring through which said 100pmembers are threaded, one loop member being connected to a side of thebag at an extremity of the open end thereof and at a lower point on rthe same side, and the other loop being similarly connected with theopposite side of the bag.

4. In a bag having an opening at one end, a

10 closing device comprising'a ring and two lengths MARTIN DE BOTELHO.
